During March 2026, Damian contributed to the mamedev/mame repository by implementing ROM definitions and metadata support for the Fighting Vipers Revision A set. Using C++ and leveraging expertise in emulation and game development, Damian expanded the ROM catalog to improve game discovery and data integrity for both end users and tooling. The work involved detailed data modeling and integration of new metadata, ensuring compatibility with existing ROM definitions. Delivered as a co-authored commit, this feature enhanced the repository’s coverage and accuracy without requiring major bug fixes, reflecting a focused approach to feature delivery and collaborative development within the project.
